Queen's Gambit Declined is probably Black's most solid response to 1.d4. This opening is especially effective when White has already committed to Nf3. In this course, GM Arjun Kalyan builds a powerful repertoire for Black based on 1.d4 Nf6 2.c4 e6 3.Nf3 d5

FM Egor Lashkin (FIDE Rating 2459) has just published his newest in-depth theoretical research - Principled Repertoire against Vienna and Ragozin. Providing an opening repertoire for White against two of the most respectable responses to 1.e4, requires hard work, subtle understanding, and a lot of dedication. After analyzing the arising positions for months, FM Lashkin managed to create practical problems for Black in all directions. Sometimes, his in-depth analysis goes to the endgame! And what is even more astonishing, the author also explains how we could put pressure in the arising endgame positions.
